Plain English summary of protocol
Background and study aims
Helicobacter pylori (HP) infection, a cause of ulcers and cancer in the stomach, and ulcers in the intestines, is frequent worldwide and treatment is well established in the general population. By contrast, little is known about how HP infection is treated among people living with HIV infection (PLWHIV). Therefore, the aim of this study is to evaluate the types of treatments used and the outcomes for PLWHIV treated for HP infection, to identify patient and disease factors that can increase the risk of treatment failure.
Who can participate?
Adult outpatients aged 18 or more who have a proven HP infection in a recent test and have not yet been treated for HP infection treatment, and who have HIV or do not have HIV, will be invited to participate in the study.
What does the study involve?
Participants will be treated for HP infection according to the current standard of care, a combination of antibiotics and proton pump inhibitor medications. Participants will be asked, using oral questionnaire about side effects (chest, digestive, general symptoms, and quality of live) during the treatment course and after cessation. Participants will then be invited back to the clinic several weeks after cessation of treatment to undergo follow-up tests in order to verify whether or not they are cured.
Participants who are HIV-infected, since October 10th, 2017 receive a support material and phone call during treatment course to hear their thoughts on the treatment side effects, and to coach their treatment.
What are the possible benefits and risks of participating?
There is no direct benefit of taking part in the study. Patients will receive the same level of care whether they choose or not choose to participate in the study, thus so there is no additional risk related to their participation in the study. The indirect benefit for the patient will be easy access to investigators and care, close follow-up with immediate support in case of side effects, and care until free of H. pylori infection
Where is the study run from?
The study will be run from University hospital Saint Pierre in Brussels (Belgium), Gastroenterology and Infectious diseases Departments
When is the study starting and how long is it expected to run for?
January 2006 to December 2023.
Who is funding the study
The study is self-funded with the support of the University Hospital Saint Pierre (Belgium).

| Scientific title | H. pylori treatment in HIV co-infected individuals with immunodepression |
| Study acronym | OHpTHIV |
| Study objectives | The treatment of Helicobacter pylori (HP) infection is widely studied, in particular among the general population. The study aims to investigate HP treatment in HIV co-infected individuals to determine whether they can be treated similarly to the general population. |

| Health condition(s) or problem(s) studied | Helicobacter pylori infection |
| Intervention | Patients included are divided into three groups: 1. Cases were HIV-positive individuals enrolled from 01/01/2006 to 31/08/2017; they receive standard of care 2. Controls were HIV-negative individuals enrolled from 01/01/2007 till 31/12/2014; they receive standard of care 3. Consecutive HIV-positive individuals recruited prospectively from 10/10/2017 to 10/09/2019; they receive HP treatment based on microbiology test only, a writing support material and phone call during the treatment course The study will run from inclusion until approximately 6 weeks after treatment completion. Types of treatment and drug dose: 1. Standard triple therapy: a PPI plus two antibiotics (amoxicillin (AMX) 1000 mg, clarithromycin (CLA) 500 mg, or metronidazole (MET) 500 mg) twice daily for 7 to 14 days 2. Sequential therapy: a PPI plus AMX 1000 mg twice daily for 5 days followed by a PPI plus CLA 500 mg and MET 500 mg twice daily for 5 days 3. Quadruple therapy pharmacy preparation of capsules: including tetracycline (TET)-chlorhydrate 500 mg plus colloidal bismuth sub-citrate 500 mg four times daily, MET 500 mg three times daily, and PPI twice daily for 10 days 4. Another quadruple therapy: single pill formulation: containing bismuth sub-citrate 140 mg/TET-chlorhydrate 125 mg/MET 125 mg (three pills to take four times daily) plus one PPI (twice daily) for 10 days 5. Concomitant therapy (CoT): PPI plus three antibiotics (AMX 1000 mg, CLA 500 mg, MET 500 mg) twice daily for 14 days. Proton pump inhibitors will be esomeprazole 40 mg, lansoprazole 30 mg, omeprazole 20 mg or 40 mg, pantoprazole 40 mg or rabeprazole 20 mg |
